BACKGROUND OF THE INVENTION Field of the Invention

The present invention relates to fans and more particularly pertains to a new canopy downdraft fan assembly for being able to direct air flow like a curtain as selected.

Description of the Prior Art

The use of fans is known in the prior art. More specifically, fans heretofore devised and utilized are known to consist basically of familiar, expected and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which have been developed for the fulfillment of countless objectives and requirements.

The prior art describes a canopy mounted to a vehicle and having an opening in the canopy with a flange circumscribed in the opening with the downdraft fan supported in the opening with the flange overlying, a perimeter of the fan. Another prior art includes a roof cap vertically offset above the canopy with a side air intake port and with the downdraft fan supported by the canopy. Also, another prior art includes a downdraft fan attached to the vehicle and a canopy mounted upon the fan. Further, another prior art includes a roll bar assembly with tubular frame members having an opening with a flange circumscribed in the opening and with the downdraft fan mounted to the frame members and a canopy having an opening and being mounted to the flange. While these devices fulfill their respective, particular objectives and requirements, the aforementioned patents do not disclose a new canopy downdraft fan assembly.

DETAILED DESCRIPTION OF THE INVENTION

With reference now to the drawings, and in particular to FIGS. 1 through 3 thereof, a new canopy downdraft fan assembly embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

As best illustrated in FIGS. 1 through 3, the canopy downdraft fan assembly 10 generally comprises a canopy assembly 20 including support members 11 adapted to be mounted upon a prime mover and including a canopy 12 having a top surface 12 a and a bottoms surface 12 b. Canopy 12 is conventionally mounted upon the support members 11 and also comprises an air flow generating assembly 13, which is connected to the bottom surface 12 b of canopy 12 and is completely covered by top surface 12 a.

The air flow generating assembly 13 includes a fan support member 14 conventionally attached to and depending from bottom surface 12 b of the canopy 12 with the fans 21-22, 24-25 conventionally supported by the fan support member 14. The air flow generating assembly 13 further includes a vent support member 29 conventionally attached to and depending from the fan support member 14 with vents 32 spaced apart and in flow communication with the fan support member 14. The fan support member 14 is a sheet of rigid material having a front end 15, a back end 16 and top surface 13 a. Intermediate the front and back ends 15, 16, the sheet of rigid material includes a recess 13 b configured with an opening 17 through the rigid material that is spaced from the top surface 13 a. Fan support member 14 further has recessed ports 18, 19 spaced apart relative to one another and spaced from the top surface 13 a and disposed through fan support member 14 proximate to the front end 15. The fans 21-22, 24-25 are conventionally mounted to the rigid sheet of material of the fan support member 14 and are conventionally connected to a power source 40. Port fans 21, 22 are each securely and conventionally disposed in a respective one of the ports 18, 19. Fan members 24, 25 are conventionally mounted proximate to the back end 16 of the sheet of rigid material of the fan support member 14. The air flow generating assembly 13 also includes a chute or plenum 26 conventionally coupled to the fan members 24, 25 and having an open distal end 27 with adjustable slats 28 spaced apart and conventionally disposed at the open distal end 27 for directing air flow created by the fan members 24, 25. The fan members 24, 25 include a pair of axial fans conventionally coupled end to end for generating greater air flow.

The vent support member 29 is a sheet of rigid material having a front end 30 and a back end 31, and also having an opening 34 disposed therethrough intermediate of the front and back ends 30, 31. The vents 32 are spaced apart and disposed therethrough proximate to the front end 30. The vents 32 are aligned with the ports 18, 19 and each of the vents 32 has adjustable louvers 33 conventionally disposed therein for selective directional flow of air generated by the port fans 21, 22. The opening 34 through the vent support member 29 is aligned with the opening 17 through the fan support member 14. The distal end 27 of the chute 26 is positioned to direct air flow through the openings 17, 34 of the fan and vent support members 14, 29. In addition cargo nets 35 securely and conventionally depend from the vent support member 29 proximate to the back end 31 of the vent support member 29 for storage.

In use, the user riding on the prime mover such as a tractor can adjust the louvers 33 and the slats 28 to direct the air flow generated from the fans 21-22, 24-25 like curtains of air flow onto oneself rather than the airflow being random to keep oneself cool during the use of the prime mover.

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the canopy downdraft fan assembly. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
